Most programs written for Windows XP also work in this version of Windows, but some older programs might run poorly or not at all. If a program written for an earlier version of Windows doesn't run correctly, use the Program Compatibility Wizard to change the compatibility settings for the program. To change settings for a program manually, use the individual program's Compatibility tab.
If changing the settings does not fix the problem, go to the program manufacturer's website to see if there is an update for the program.
Do not use the Program Compatibility Wizard on older antivirus programs, disk utilities, or other system programs because it might cause data loss or create a security risk.
Open the Program Compatibility Wizard by clicking the Start button , clicking Control Panel, clicking Programs, and then clicking Use an older program with this version of Windows.
Follow the instructions in the wizard.
If you cannot install a program, insert the installation disc for the program and, using the wizard, browse to the program's setup file, usually called Setup.exe, Install.exe, or something similar. The wizard is not designed to work on programs that have an .msi file name extension.
To change compatibility settings manually for a program, right-click the icon for the program, click Properties, and then click the Compatibility tab.
